Improvement in plows



UNITED STATES "PATENT OFFICE HORATIO GALE, OF ALBION, MICHIGAN.

IMPROVEMENT IN PLOWS.'

Specification forming part of Letters Patent No. 103,038, dated May 17,1870.

' l, HORATIO GALE, of the village of Albion,

j the mold-board, whereby, in connection with an adjustable stud, themold-board may be effectually stayed without any special fitting ofconnectingbraces or other supports, the advantages of which arrangementwill be hereinafter ufully described.

`Figures l and 2 are perspective views of a plow from different pointsin which my invention is embodied.

In the drawings,']3 is the beam, and L the land-side, and they are shownas forming only one single piece of casting;but my invention is equallyapplicable to plows having wooden beams and cast land-sides firmlyconnected together in any suitable way.

C is the mold-board, which does not differ materially from those inordinary use, and may be connected with the land-side in front in anywell-,known approved manner. As there is no attachment in my arrangementto the hinder part ofthe mold-board, its interior convex face may becast perfectly even, and without the usual recesses, loops, or otherprojections, except, perhaps, two short ribs to form a groove, for apurpose to be hereinafter explained.

v a is an extension or arm of the land-side, to which the left handle,H, is bolted. D is the hanger-brace, which, for the purpose ofconferring strength as well as symmetry, I usually con struct in anarched form. This han gerbrace is provided with end Bauges, throughwhich it isbolted to the land-side, or land-side and beam, in such amanner that the arched central` portion will befprojected laterally, tobring it into a proper relative position for the attachment to it of theright-hand plow-han-r dle, H. b j

The handles, with the exception of the usual end curves to hold by, aremade straight, and the lower ends, being chamfered and fitted togetherto give the proper filare, are inserted between two projecting fianges,j', cast on the land-side, and are secured thereto by a pivotbolt, b, insuch manner that the handles are capable of vibrating on the bolt forvertical adjustment. The seat for the foot of the left handle againstthe land-side must be properly projected therefrom, so that whenconnected the lhandle will have the proper fiare or set. Anadjusting-slot, i, is formed in the land-side arm a, and also one in thehanger D, both` slots being arcs of al circle struck from the point b.

The two handles H and H', being tted as aforesaid, and connected with astay, round, l

as at j, have their lower ends inserted between the fianges. f, and arethere secured to the land-side by the bolt b. The left handle isadjustably secured to the land-side by albolt at e, passing through theslot, and the right handle, lying against the right side of thehanger-brace D, is similarly secured by the bolt e'. Between the righthandle and the mold-board a slotted plate, p, carrying a projectingstud, S, is interposed, and is adjustably secured to the right handle bythe same bolt that screws the handle to the hanger-` brace. 4

In my mode of securing the handles and staying the mold-board, it is notnecessary to erect thel entire plow for transportation or storage; for,should the set of' the mold-board in relation with the land-side varyv alittle, as it generally does in different plows, the staying stud-platebeing the closing piece in the erection, the end of the stud willalwaysfind its bearing against the mold-board, on the plate being slidalongside the handle in 'the wedge-shaped interval, until the end of thestud comes in contact. When the handle is adjusted to a suitable height,the whole is secured by one bolt, and in this way all fitting or otherskilled labor is entirely dispensed with in the final erection of allthe parts. If deemedA best for additional strength or security, the endofthe stud S may enter a groove (not shown) formedby casting two ribs onthe mold-board, as aforesaid.

I'lows, when erected complete, are bulky A and expensive articles ofstorage and transportation. My arrangement permits them t0 be stored ortransported in detached parts-as, for instance, the beam and land-sidewith the hanger-brace, tted and connected to them in the shop, may formone part, the mold-board another, and the two handles, fitted and boredto gage, anotherand in this way a great saving in storage and freightagebe effected.

My arrangement, in addition, permits the main fitted parts of thehandles to be made straight, and also allows each handle to beseparately adjusted in height, which is sometimes a great convenience inoperating aplow.

I do not claim, broadly, pivoted plow-handles adjustable in slots, asthere is a plow in which the left handle is pivoted to the landside, andthe right handle is attached in the same manner to the mold-board, thehandles being adjustable in slots in the land-side and mold-board,respectively.

I claim as my invention- -l. The detachable brace D, provided with aslot, i, in combination with the land-side and the handle H', as and forthe purpose set forth.

2. In combination with the right handle of a plow attached to a brace,D, as described, the adjustable sliding plate p, having thereon a studor post, S, for the purpose set forth.

HORATIO GALE.
